Title (EN) INLET FOR AXIAL FAN
(FR) ENTRÉE POUR VENTILATEUR AXIAL
Abstract:
(EN) A fan assembly (10) includes a shrouded fan rotor (18) having a plurality of fan blades (22) extending from a rotor hub (24) and rotatable about a central axis (20) of the fan assembly, and a fan shroud (26) extending circumferentially around the fan rotor (18) and secured to an outer tip diameter of the plurality of fan blades (22). A fan casing (16) encloses the shrouded fan rotor (18). The fan casing (16) defines a fan inlet (30) of the fan assembly and includes an inlet extension (54) at an outer diameter of the fan casing, extending axially upstream of a conventional bell mouth inlet (58), relative to a direction of airflow through the shrouded fan rotor (18).
(FR) Ensemble ventilateur (10) comprenant un rotor caréné (18) de ventilateur possédant une pluralité d'aubes (22) de ventilateur (22) s'étendant à partir d'un moyeu (24) de rotor et pouvant tourner autour d'un axe central (20) de l'ensemble ventilateur, et un carénage (26) de ventilateur s'étendant de manière circonférentielle autour du rotor (18) de ventilateur et fixé à un diamètre de pointe extérieur de la pluralité d'aubes (22) de ventilateur. Un carter (16) de ventilateur renferme le rotor caréné (18) de ventilateur. Le carter (16) de ventilateur délimite une entrée (30) de ventilateur de l'ensemble ventilateur et comprend une extension d'entrée (54) au niveau d'un diamètre extérieur du carter de ventilateur, s'étendant axialement en amont d'une entrée de pavillon classique (58), par rapport à une direction d'écoulement d'air à travers le rotor caréné (18) de ventilateur.
